Cloud Reikey alto saxophone mouthpiece, 4*3. The tip opening is relatively narrow, making it very easy to play for those who usually play classical or wind ensemble music. Among the Reikey mouthpieces, this one has a moderate resistance similar to a classical mouthpiece, and I was able to play it without any discomfort even when switching mouthpieces mid-concert. Since my main jazz/pop mouthpiece, like my classical one, has become fixed, I am putting this up for sale.
